Summary

Fixes #1405: inline comments are posted twice when classify_inline_comments is enabled (the default).

When buffering is on, create_inline_comment buffers calls without confirmed=true and replies "Set confirmed=true to post immediately." The model frequently reacts by re-issuing the call with confirmed=true, which posts the comment live, but the original buffered entry stays in /tmp/inline-comments-buffer.jsonl. The post-buffered-inline-comments step then replays it, so every inline comment lands twice (~15-25s apart). For Vertex/Bedrock users (no ANTHROPIC_API_KEY) the whole buffer is replayed unconditionally, but the duplicate happens regardless of classification because the buffered entries are genuine comments.

Fix

This implements option 1 from the issue: reconcile the buffer on a live post. After a confirmed=true comment is created, any buffered entry matching the same path + line + startLine + body is removed, so the replay step can no longer post a duplicate.

The reconciliation is extracted into src/mcp/inline-comment-buffer.ts. The MCP server module starts a stdio server (and process.exits on missing env) at import time, so the logic is pulled into an import-safe module to keep it unit-testable.

Tests

test/inline-comment-buffer.test.ts (5 cases): removes the matching entry, removes repeated copies, leaves the buffer untouched when nothing matches, no-ops when the buffer file is absent, and preserves lines that cannot be parsed.

Verification (run locally)

  • bun test — full suite 734 pass / 0 fail (5 new tests included).
  • bun run typecheck (tsc --noEmit) — clean.
  • prettier --check — clean on all changed files.

Notes

This is the minimal root-cause fix for the re-call path. The issue also suggests dedup in the post-step (idempotency across retries / gh api posts) as defense-in-depth; happy to add that here or in a follow-up if preferred.

When classify_inline_comments is enabled, create_inline_comment buffers calls
without confirmed=true. The model frequently re-issues the call with confirmed=true
after reading the buffered reply, which posts the comment live but leaves the
original buffered entry behind. The post-session replay step then posts it again,
so every inline comment lands twice.

Reconcile the buffer on a live post: after a confirmed comment is created, remove
any buffered entry matching the same path, line, startLine and body so it cannot be
replayed. Extracts the reconciliation into src/mcp/inline-comment-buffer.ts (the MCP
server module starts a server on import) and adds unit tests.
